Objective To explore the relationship between self- management and DOSE index for patients with chronic obstructive pulmonary disease (COPD). Methods The convenient sampling and Pearson correlation analysis was used in the study,a total of 81 patients was investigated with Self- Management Scale (SMS) for COPD patients and DOSE index. Results The relationship of symptom management and DOSE index for COPD patients was a positive correlation (r=0.259, P<0.05);with self- efficacy was a negative correlation(r=-0.288, P<0.05).But self- management, daily life management, emotion management and information management with DOSE index were no correlation (P>0.05). Conclusions Through health education, nurses should strengthen to effectively help patients manage symptoms, enhance self- efficacy, improve the patients′quality of life.

Alzheimers disease (AD) is a progressively and retrogressively neurodegenerative disorder of central nervous system severely threatening the aged. The studies of animal models, which share the very similar neuropathological characteristics with human, provide tools for the understanding of the etiology, mechanisms and medicine screening of AD. The distribution and chemical composition of amyloid-beta (A- beta) peptide -positive deposits were investigated in various non-human primate models. Various proportions of A- beta deposits contained cholinesterase activities, apolipoprotein E(ApoE) and alpha1-antichymotrypsin immunoreactivity. Alterations in the basal forebrain cholinergic system have been widely studied, but the magnitude of decline and relationship to cognitive impairment are still a matter of debate. This article also includes the latest research of the changing on tau, subtle structural alterations in axons, and neurofibrillary tangles (NFT) in the brain tissues of the non-human primate models.

Objective To evaluate the potential effect of HLF (Hawthorn leave flavonoids, w/w, 80% flavonoids) against thrombus formation, effect of HLF on hypoxia-treated human umbilical vein endothelial cell (HUVECs) was studied. Method The levels of cytotoxicity and NO upon HUVECs were studied by flow cytometry. Moreover, the level of calcium ion in HUVECs was examined through laser scanning confocal microscopy. Result Data from this study showed that HLF at concentrations of 5 μg/ml and 10 μg/ml decreased the cytotoxicity of hypoxia to HUVECs (P<0.05, P<0.01). The intracellular levels of NO and calcium ion were downregulated by HLF at concentrations of 5 μg/ml (P<0.01; P<0.01) and 10 μg/ml (vs control, P<0.01; P<0.01) too. Conclusion Results observed suggest that HLF protect HUVECs from hypoxia partly through its regulative effect on NO and calcium ion levels.

Objective To investigate the effect and safety of urinary kallidinogenase on acute cerebral infarction.Methods One hundred and sixty-four patients with acute cerebral infarction were randomly divided into two groups:treatment group with urinary kallidinogenase(86 cases)and control group (78 cases).According to Chinese guidelines for prevention and management cerebrovascular disease,two groups were treated with basic therapy,such as antiplatelet,neurologic protection,blood pressure control,and so on.On basis of control group,treatment group Was administrated intravenous injection of urinary kallidinogenase 0.15 PNA U per day for 10 days.The primary efficacy Was evaluated by the National Institutes of Health Stroke Scale(NIHSS)score and Barthel index.Results The score of NIHSS and Barthel index at 15 days after treatment in the treatment group were higher than those in the control group[(6.67±3.02)scores vs(7.42±3.02)scores;75.36±23.56 vs 68.36±22.36,P＜0.05].Urinary kallidinogenase could significantly reduce neurological deficits in big artherosclerosis type by TOAST typing.Conclusion Urinary kallidinogenase may be effective and safe in the treatment of acute cerebral infarction.

As the important content of excellent quality nursing service, the performance appraisal of nursing staff was closely interrelated to their income distribution, professional title promotion and excellence choosing. Performance appraisal was the requisite part of nursing resource management. This study gave an overview about conception and development of nursing staff′s performance appraisal and summarize key performance indicator,balanced score card,SMART principle and 360 degrees performance appraisal, which was mainly used in domestic hospital. It suggested nursing manager should have complementary advantages of them and utilize foreign mature methods to explore and improve our countries performance appraisal of nursing staff and formulate the system which was in keeping with China′s national conditions.

Objective:To study the cytotoxicity of PHEMA /CPC composite hydrogel.Methods:L929 cells were cultured by RP-MI1 640 with 1 0% fetal bovine serum(blank control),with PHEMA /CPC extraction(experimental group),high density polyethy-lene(HDPE)extracts(negative control)and 5% DMSO(positive control)for 24,48 and 72 h respectively.The cell proliferation was examined by MTT assay.Cell apoptosis was detected by flow cytometry and Annexin V-FITC /PI kit.Results:The A value of positive control group decreased with the increase of culture time(P <0.01 )(between experimental and negative control groups,P>0.05).The cytotoxicity of the experimental group was grade Ⅰ.That of other groups increased with the increase of culture time. Cell apoptosis(%)in PHEMA /CPC composite hydrogel group and blank group was 4.21 ±0.30 and 4.89 ±0.39 respectively(P>0.05).Conclusion:Injectable PHEMA /CPC composite hydrogel has no cytotoxicity and no effect on cell apoptosis.

0.05), except PYM-AMS of 1.130 mg/ml and PYM of 300 ?g/ml at 24 h.In the same group and at the same exposure time,higher dose of the corresponding agents showed higher growth inhibition ratio(P0.05).At the same doses 48 h exposure of PYM-AMS or PYM gave higher apoptosis rate than 24 h exposure(P

Objectives:To investigate the characteristics of clinical changes during maintenance therapy of chronic periodontitis.Methods:22 patients with chronic periodontitis were enrolled in a 9-month maintenance care program after non-surgical periodontal therapy.Oral hygiene instructions together with supra-and sub-gingival scaling and root planing were carried out every 3 months.Clinical parameters including probing pocket depth(PPD),probing attachment level(PAL),and bleeding on probing(BOP) were recorded at baseline and each re-examination point.Results:The mean PPD decreased by 0.44 mm,PAL increased by 0.38 mm and BOP point number decreased by 18.94%.The recoveries were mainly observed during the first 3 months.Sites with ≥4 mm pocket at baseline exhibited a greater percentage of pocket deepening than those with initial shallow pocket.The incidence of the sites with PPD deeping of posterior teeth increased more than that of anterior teeth(P
